Bazel: Work behind a proxy

[cuihenggang]

I'm using bazel to build an open source project, and it will download some third-party packages. My machine connects to the outside world with a proxy, and I set the "http_proxy" and "https_proxy" environment variables to use the proxy.

I find bazel is not able to download the third-party packages using my proxy. I tried manually downloading the packages using "wget" and it works. So I'm wondering how do I let bazel use a proxy?

Thanks,
Cui

Hi,

I try to compile tensorflow on F28, using Bazel 0.22 from Fedora Copr. I have http_proxy and https_proxy set and I added no_proxy to avoid having proxy on localhost.
I have the same kind of issue as this old bug from 2015 : bazel can't fetch "http_archives" but those urls are perfectly downloadable as I use curl or wget.
What should I do to have bazel taking care of my proxy and using it ? I had a look at isse #587 (which is listed above), it does not look the same.

Information about my issue:
$ bazel -h
INFO: Invocation ID: 86688149-5750-490b-b67e-c6066311487f
[bazel release 0.22.0- (@non-git)]
(...)
My proxy is 10.200.255.254:1080, I have http_proxy, https_proxy, HTTP_PROXY and HTTPS_PROXY pointing to it, no_proxy and NO_PROXY have value localhost,127.0.0.1
I really don't know what to do. It seems like the proxy setting : is misunderstood somewhere.

Same problem here.

Finally, I downloaded every "bazel package" using wget into a local directory (all in the same directory), and then I ran bazel using the --distdir= command line option. Bazel went and get the package in the "distdir" and not on the internet, through the proxy. This is no fix, this does not solve the problem, but it's a usable (but quite annoying) workaround.

@phdeniel I'm building TensorFlow version 1.9, which require bazel 0.11.0 (https://www.tensorflow.org/install/source#tested_build_configurations)
But it seems that --distdir is not available for bazel 0.11.0 yet, do you have any work around of this problem for that version?

build tf 2.1 with bazel 0.29.1 now... encountered this issue at the beginning because I exported http_proxy (and https_proxy) =localhost:1080, and bazel doesn't recognize it. everything works fine after I changed http_proxy and https_proxy to http://localhost:1080
